Similar to boom roasted, only much more insanely awesome and impressive. Can be only be used to describe a diss or burn that was given with such power and finesse that it reached a whole new level of raw awesomeness. If awesome and chuck norris had a baby, it would be boom toasted.

An expression interjected immediately after communicating something complimentary, slightly or very cheesy, nice, and/or possibly suck-up-ish to someone's face (most likely in a group setting) about that person. (Similar to a formal toast at a wedding or special event.)

boy: "Hey, Candace, there is this girl in one of my classes who could be your long lost twin!"

girl: "Haha that's cool. You should befriend her; she can be like my replacement while you're away at college."
